Tell Tale Lamps
Bulb Check
In order to check that the warning systems are operative, all the tell tale lamps should light for two
seconds following ignition switch on. If any lamp should fail to light, there is likely to be a fault on that warning
circuit.
Seat Belt Tell Tale (red)
As a reminder to fasten the seat belts, the seat belt icon in the tachometer will flash red for about eight
seconds following ignition switch on, and will then be extinguished.
Oil Pressure Tell Tale (red)
This red tell tale warns of low engine oil pressure. The lamp will be lit whenever the ignition is on and the
engine is stopped, but should extinguish as soon as the engine is started. If the lamp fails to go out after engine
start up, or comes on when the engine is running, stop the engine immediately and do not restart until the cause
has been investigated and rectified. Continuing to run the engine with little or no oil pressure could cause
major internal damage, possibly resulting in seizure.
